SUBSONIC AND TRANSONIC PRESSURE DISTRIBUTIONS

AROUND A BLUFF AFTERBODY IN THE WAKE OF A 120' CONE

FOR VARIOUS SEPARATION DISTANCES

By James Wayne Sawyer and Charles F. Whitcomb Langley Research Center

SUMMARY

A wind-tunnel investigation w a s conducted at free-stream Mach numbers from 0.20 to 1.00 and Reynolds numbers, based on maximum afterbody diameter, from 2.25 X lo6 to 6.9 X lo6 on solid models of an attached inflatable decelerator (AID) concept. Tests were conducted to obtain static and ram surface pressure distributions about the basic shapes and at various separation distances between the 120' conical forebody and the inflated afterbody shape.

' Ram pressure coefficients, approximately equal to stagnation values, were obtained along the front surface of the bluff afterbody shape, with and without the cone, for all Mach numbers tested. However, separation of the cone from the afterbody resulted in a degradation of the ram and static pressure coefficients. Static results obtained with the cone separated various distances from the afterbody indicate that extraction of a payload from a conical forebody by means of an attached inflatable decelerator is possible provided that the mass of the payload plus decelerator is not too great. For Mach numbers of 0.70 o r less, the mass of the payload plus decelerator must be less than 3.5 times the mass of the forebody. Additional tests a r e needed to determine the maximum allowable mass of the payload plus decelerator for Mach numbers greater than 0.70.

INTRODUCTION

One of the uses envisioned for the attached inflatable decelerator (AID)concept discussed in references 1to 6 and illustrated in figure 1 is on unmanned planetary atmospheric entry systems designed to deliver a scientific payload to the surface of a planet. One such system has the payload and inflatable afterbody packaged behind a large-angle cone forebody in transit to the planet; the cone serves both as a heat shield and as a decelerator on entry. During entry the inflatable afterbody is deployed at supersonic speeds to augment the drag of the cone.

For some missions (such as an unmanned expedition to Mars) it may be desirable to jettison the cone before touchdown. The inflatable afterbody may then be required to

ll11111ll11llIll I I1

extract the payload from the cone. Mission requirements may dictate that the cone be jettisoned while the decelerator is traveling at either subsonic or supersonic speeds. The investigation of reference 6 was conducted to study the feasibility of separating the cone from the afterbody at a Mach number of 3.0. The present investigation was carried out to evaluate payload separation at subsonic and transonic speeds.

A sting-mounted pressure-distribution model of the AID was tested in the Langley 16-foot transonic tunnel at free-stream Mach numbers from 0.20 to 1.00 and Reynolds numbers, based on maximum afterbody diameter, from 2.25 X lo6 to 6.90 X lo6. The tes ts were conducted to obtain ram (total recovery pressure) and surface pressure distribution data on the AID at various separation distances between the cone and afterbody.

MODELS, APPARATUS, AND TESTS

Models

A sketch of the pressure-distribution model is shown in figure 2. The forebody was a spherically blunted 2 = 0.122 120' cone with a sharp shoulder at the cone base

(:brim. The model was constructed so ithat it could be tested with o r without the burble fence and cone forebody. When the forebody was not attached, the sting cavity on the front of the afterbody was filled with a sharp-pointed 135' cone so that its surface faired into the afterbody surface. The cone forebody was constructed of stainless steel with the surface polished to a finish of approximately 250 nm, rms. The afterbody and the burble fence were constructed of cherry wood. The surface was impregnated with epoxy resin

and then polished. The afterbody was constructed without the lobes shown in figure 1. The cone radius was 0.44rb, and the maximum radius of the burble fence was 1.1Orb. Thus, the total projected frontal area including the burble fence was 6.2 times that of the cone frontal area. The leading edge of the burble fence was 0.045rb upstream of the maximum radius of the afterbody. A sting with a diameter of 0.20rb supported the AID model in the tunnel. Three stings with diameters of 0.14dc and with different lengths were used to vary the separation distance between the cone and the AID. Model coordinates are given in table I.

Static- and ram-pressure orifices were installed in the pressure -distribution model at the locations indicated in figure 2 and in tables I and 11. Static pressures were measured on the cone at 10 stations along the outer surface and at 7 stations along the inner surface, at 42 stations around the afterbody, and at 11 stations around the burble fence. These static orifices were located in a plane containing the model axis. (See fig. 2.) Ram pressures were measured at five stations along the afterbody at a distance of 0.64 cm above the surface. These orifices were staggered circumferentially to avoid mutual interference.

Test Facility

The present investigation was conducted in the Langley l6-foot transonic tunnel, which is a single-return, continuous-flow wind tunnel, which operates at atmospheric stagnation pressure. The slotted octagonal test section is 4.73 meters across the flats and may be operated continuously at Mach numbers from approximately 0.2 to 1.3. Reference 7 contains a description of the tunnel and its main drive system.

Tests

The AID with the burble fence was tested at cone separation distances of 0.00, 0.11, 0.34, 0.57, 0.91, and 1.36 cone diameters and with the cone removed (dbC-- a). The AID

without the burble fence was tested with the cone removed. All tests were conducted with the model oriented at 0' incidence with respect to the flow direction. The Mach number was varied between 0.20 and 1.00. The resulting Reynolds number, based on the maximum afterbody diameter (2rb), varied between 2.25 X lo6 and 6.90 X lo6 as indicated by the typical curve shown in figure 3. The model blockage area ratio in the wind tunnel was about 0.013 for the AID and 0.011 for the AID without the burble fence. At such large blockage ratios, the data at M, = 1.00 may be subject to substantial wind-tunnel wall interference effects.

The test procedure consisted of slowly increasing the tunnel velocity until the desired test Mach number was reached. After the flow conditions had stabilized, the necessary data were taken and the Mach number was then increased to the next higher value. This procedure was repeated until the maximum Mach number was obtained, and

4

then a similar procedure was followed while the Mach number was decreased. Data were taken at Mach numbers of 0.20, 0.30, 0.40, 0.50, 0.60, 0.70, 0.80, 0.85, 0.90, 0.95, and 1.00 while the Mach number was increasing, and at check Mach numbers of 0.80, 0.60, 0.40, and 0.20 while the Mach number was decreasing. Figure 3 shows that the resulting Reynolds number for a certain Mach number differed, depending on the direction from which the test condition was approached. The variation in Reynolds number results from a change in the temperature of the airstream with time during tunnel operation.

All model pressures were recorded by using three automatic pressure scanner units, each with 48 pressure channels. Each pressure scanner unit was connected to a strain-gage pressure transducer calibrated within rt350 N/m2. Each scanner unit was operated at a scan rate of two channels per second. The output from the transducers was recorded and reduced to coefficient form at the Langley central digital data recording facility.

RESULTS AND DISCUSSION

Pressure Distributions on AID Shape

A typical surface pressure-coefficient distribution obtained for the attached inflatable decelerator (AID) with the cone attached is shown in figure 4, where the Cp values a r e represented by scaled arrows perpendicular to the configuration surface. Arrows pointing toward and away from the configuration surface indicate positive and negative values of Cp, respectively. The data indicate the following flow characteristics: The flow expands from the stagnation point at the model nose to a station upstream of the leading edge of the burble fence where the presence of the burble fence forces a recompression of the flow to nearly constant Cp values on both the afterbody and the fence near their juncture. The flow then expands rapidly along the front surface of the fence and separates approximately at the maximum diameter of the fence, where the Cp value becomes constant all along the rear surface of the afterbody.

Surface pressure coefficients obtained for free -stream Mach numbers between 0.20 and 1.00 a r e shown in figure 5 as a function of the surface coordinate r/rb for the AID with the cone attached. Local Mach number distributions along the front surface of the configuration a re also shown in figure 5 and were calculated by using the free-stream stagnation pressure and the local measured surface pressures. All pressure data obtained in this investigation are given in tables I and II. The data taken after the desired free-stream Mach number was approached from a larger and from a smaller value show generally good agreement. Therefore, in most figures the data presented a re those taken when the desired Mach number was approached from a smaller value. However, when significant differences do exist, both sets of data a r e presented. The pressure-coefficient

distributions shown in figure 5 are similar for all Mach numbers investigated. In general, increasing the Mach number resulted in higher Cp values on the front of the AID upstream of the maximum diameter of the burble fence but had no significant effect on

the Cp values on the base of the configuration. The flow separated from the base of the AID at approximately the maximum diameter of the burble fence for all Mach numbers tested and was not sensitive to the direction from which the Mach number was approached.

The local surface Mach number in figure 5 increases as the flow expands along the front surface from near zero at the nose to a maximum at a position slightly upstream of the maximum fence diameter. The maximum local Mach number becomes sonic at a free-stream Mach number of approximately 0.60. The irregular variation of the local Mach number near the fence-afterbody juncture is due to the recompression of flow that takes place as the result of the large change in the surface slope produced by the fence.

Effect of Removal of Burble Fence on Pressure Distributions

The burble fence is discussed in reference 4 as being required at subsonic speeds to maintain uniform flow separation at the configuration base for dynamic stability. Pressure -coefficient distributions were measured with the burble fence and cone removed from the afterbody, and typical results are presented in figure 6, where the Cp values a r e represented by scaled arrows perpendicular to the configuration surface. Arrows pointing toward and away from the configuration surface indicate positive and negative values of Cp, respectively. The pressure coefficients decrease along the afterbody surface to a minimum value slightly in front of or at the maximum diameter of the model. Slightly downstream of the minimum Cp value there is a sharp rise in the Cp values followed by an approximately constant distribution on the base of the configuration. This behavior is indicative of a separated flow region. Comparison of the Cp distributions obtained for the afterbody shows that considerably more expansion of the flow is obtained about the front surface of the afterbody without the burble fence than with the fence attached.

Pressure-coefficient distributions obtained with the burble fence removed from the afterbody a re presented in figure 7 as a function of r/rb for each free-stream Mach number tested. In general, the Cp distributions show similar variations with r/rb for all Mach numbers tested. For Mach numbers of 0.50 and above, base flow separation is clearly defined by the pressure distributions and takes place at the maximum diameter of the configuration. The Cp values in the separated flow region increase slightly toward the axis of the configuration. Increasing the Mach number above 0.50 increases the Cp values on the front surface of the AID and gives slightly more uniform Cp values on its base. For Mach numbers of 0.20, 0.30, and 0.40 (figs. 7(a), (b), and (c)), the pressure coefficients in the separated flow region at the base of the configuration a re

6

somewhat variable, and the point at which flow separation occurs on the configuration is downstream of the maximum diameter and is dependent on whether the test Mach number is approached from a smaller (solid curve) or larger (dashed curve) value. This sensitivity of separation-point location to the direction in which the Mach number is approached is attributed to the large radius of curvature near the maximum diameter, which allows the separation point to move relatively large distances, and possibly to flow hysteresis effects. The observed changes in separation-point location could produce dynamic motion if the body were free to translate o r pitch. These results are in agreement with unpublished data obtained during the investigation of reference 5 on a fabric model where it was found that for Mach numbers less than 0.50, violent oscillations of the AID occurred if a burble fence was not attached to the afterbody.

Pressure Distributions for Separation of Cone and Afterbody

Static pressure.- Surface pressure-coefficient distributions obtained for the AID with the cone separated from the afterbody by 0.11, 0.34, 0.57, 0.91, and 1.36 cone diameters and with the cone removed are presented in figure 8. Curves faired through the measured pressure data are for representative Mach numbers throughout the range investigated. For small separation distances, pressure coefficients obtained on the base of the cone were constant and were identical with those obtained on the front of the after-body. (See, for example, figs. 8(a) and 8(b).) This result indicates that a cone-wake separated flow region extends between the two bodies. The flow reattaches to the after-body at the point where the pressure coefficient curves peak slightly downstream from the constant-pressure region. Thus, the wake separated flow region is shaped like a cone frustum since the region covers a larger area on the afterbody than on the cone base. This behavior is similar to that shown in figure 4(b) of reference 6. Increasing the distance between the cone and the afterbody results in the wake separated flow region covering a larger area of the afterbody surface, greater expansion of the flow about the cone surface, and Cp values on the front surface of the afterbody even lower than those obtained on the base of the cone. Base flow separation occurs at the maximum diameter of the fence for all configurations and flow conditions investigated.

For small distances between the cone and the AID, increasing the Mach number increases the pressure coefficients along the front surface of both bodies and has little effect on the extent of the wake separated flow region and base-pressure coefficients. For greater distances between the cone and the AID, increasing the Mach number results in the wake separated flow region covering a greater a rea of the afterbody.

For 6= 1.36 (fig. 8(e)), the pressure coefficients on the base of the cone and on dC

most of the front surface of the afterbody for M, = 0.30 a r e considerably more irregular than for the other separation distances and Mach numbers presented. This irregular

7

11l1111II I I I I I I I

behavior indicates that the separated flow region is in the process of changing from a cone-frustum shape to a more converged shape. A similar change in the shape of the separated flow region was obtained for the same configuration at a Mach number of 3.0 in reference 6 but at a much larger cone-afterbody separation distance.

The pressure distributions obtained for the cone removed from the AID (fig. 8(f)) a r e similar to those obtained with the cone attached to the afterbody (fig. 5) and show similar variations with Mach number. However, for 0 S r / r b S 0.50, the pressure coefficients are slightly higher and less irregular than those obtained with the cone attached.

Ram pressures.- The ratios of ram pressure to total pressure are shown in figure 9 as a function of r/rb for each separation distance and representative free-stream Mach number tested. For the cone attached to the afterbody (fig. 9(a)),ram pressures along the front surface of the afterbody are approximately constant and equal to the stagnation pressure for all Mach numbers tested, For -6 = 0.11 (fig. 9(b)), the ram pres

dC sures at small values of r/rb are less than stagnation pressures because the orifices a r e located within the cone-wake separated flow region, whereas at large values of rIrb, stagnation pressures are obtained. Increasing the free-stream Mach number reduces the ram pressures for those locations where the probes are embedded in the separated flow region. This behavior is due to the separated flow region covering a larger area of the afterbody, and thus, the probes a re embedded deeper in the separated flow region as the free-stream Mach number is increased. As 6/dc is increased to 0.34 (fig. 9(c)), the separated flow region covers a larger area of the afterbody, and thus, ram pressures equal to stagnation pressures a re obtained over a smaller area of the afterbody. For 0.57 5 6 5 1.36 (figs. 9(d), (e), and (f)), all the r a m pressures are affected by the cone

dC wake and are lower than the free-stream stagnation values. However, for the cone removed (fig. 9(g)), ram pressures equal to stagnation pressures were again obtained along the front surface of the afterbody as expected.

AID Pressure Drag Coefficients

Drag coefficients obtained by integration of the Cp distributions obtained for the AID with the cone attached (fig. 5), the AID (fig. 8), and the AID without the fence attached (fig. 7) are shown as a function of Mach number in figure 10. Also shown for comparison a re force test data obtained from reference 5 on a flexible AID model of similar shape. Drag coefficients for the AID with the cone attached (circle symbols) and for the AU) (diamond symbols) show relatively smooth increases with increasing Mach numbers, whereas the drag coefficients for the AID without the fence (square symbols) show similar but much more errat ic variations. For the AID with the cone attached, the drag coefficients show an increase with Mach number from a value of 0.50 at M, = 0.20 to a value of 0.90 at M, = 1.00, The data from reference 5 show much higher drag coefficients at

8

the lower Mach numbers and a slightly higher value at M, = 1.00 than the present,AID data. The discrepancy between the two sets of data is thought to be due to the difference in the actual configuration shapes tested. The configuration tested in reference 5 was designed to have the same shape as the configuration of the present investigation at supersonic Mach number; however, the AID of reference 5 was constructed of lightweight fabric and was inflated by four ram-air inlets mounted on the AID canopy. Since the shape is dependent on the pressure distribution, the subsonic air loads on the flexible model resulted in an actual configuration shape that was somewhat blunter than the design shape of the present investigation.

Pressure Drag Performance in Cone Wake

Drag coefficients obtained by integration of the pressure distributions about the. cone and the afterbody are presented in figure 11 for each cone-afterbody separation distance and Mach number investigated. In general, the cone drag coefficients first increase in value and then become constant as the cone-afterbody separation distance increases, whereas the afterbody drag coefficients first decrease to a minimum value and then start increasing again. For free-stream Mach numbers greater than 0.80, a minimum value was not obtained within the range of separation distances investigated. However, since higher drag coefficients a r e obtained with the cone removed

(d"c -= 9 than at -6 = 1.36,

dC it is evident that the drag coefficients do follow the same trend for all Mach numbers tested. Increasing the free-stream Mach number also results in an increase in the drag coefficients for both the cone and the afterbody. For a free-stream Mach number of 0.20 (fig. 9(a)) and -6 = 1.36, the drag coefficients obtained when the Mach number was

dC approached from a larger value (solid symbols) are considerably different from those obtained when the Mach number was approached from a smaller value (open symbols). This difference is reflected in the pressure-coefficient distributions by lower Cp values on the base of the cone and on much of the front surface of the afterbody when the test Mach number was approached from a larger value than when it was approached from a smaller value. These differences in pressure are due to changes in the separated flow region between the cone and the afterbody as the result of the small difference in Reynolds number or flow hysteresis effects. The separated flow region between the cone and the afterbody may be in the process of changing from a diverged shape to a more converged shape, and thus, small flow changes have a significant effect on the shape of the separated flow region and the pressure coefficients in that region.

Payload Extraction From Cone

Since it may be desirable to jettison the cone before landing, it is of interest to determine the maximum payload mass which may be separated from the cone by the AID

9

at subsonic speeds. This has been done by using the pressure drag coefficients of figure 11and an AID-to-cone frontal-area ratio of 6.2 to compute values of afterbody-tocone mass ratios for which the two bodies will have the same acceleration and, thus, will not separate any farther (from purely static considerations). The loci of points defining the maximum static separation distance of the two bodies is presented in figure 12, in which the ratio of the mass of the AID plus payload to mass of the cone is plotted against separation distance. The region below the curves indicates conditions under which the cone and afterbody will continue to separate. Curves are presented for free-stream Mach numbers representative of those tested and indicate that for Mach numbers of 0.70 or less the two bodies will continue to separate if the ratio of the mass of the AID plus payload to the mass of the cone is less than approximately 3.5. For Mach numbers greater than 0.70, the separation boundaries did not reach a minimum for the range of separation distances investigated, and additional tests a r e needed to determine the maximum allowable mass of the AID plus payload. For comparison purposes, the mass ratio in the Viking program is approximately 5, and from these data obtained at steady-state conditions, separation of the Viking payload and cone with this AID configuration may not occur at subsonic speeds. It should be noted, however, that the curves of figure 1 2 would represent a lower bound since separation dynamics and skin-friction drag have not been considered. Also, increases in AID-to-cone a rea ratio result in direct increases in mass ratio allowable for separation.

CONCLUSIONS

A wind-tunnel investigation was conducted at free-stream Mach numbers from 0.20 to 1.00 and Reynolds numbers, based on maximum afterbody diameter, from 2.25 X l o6 to 6.90 x 106 on solid models of an attached inflatable decelerator (AID) concept. Tests were conducted to obtain static and ram surface pressure distributions about the basic shapes and at various separation distances between the 120° conical forebody and the AID. The results indicate the following conclusions:

1. For the AID with the cone attached, the local Mach number becomes sonic at a point on the body for a free-stream Mach number of approximately 0.60.

2. Drag coefficients for the AID with the cone attached show a smooth increase with increase in Mach number from a'value of 0.50 at a free-stream Mach number of 0.20 to a value of 0.90 at a free-stream Mach number of 1.00.

3. Ram pressure coefficients were approximately equal to stagnation values along the front surface of the AID, with and without the cone attached, for all Mach numbers tested.

10

4. For the conical forebody separated from the afterbody, r a m and static pressure coefficients on the forward part of the afterbody are reduced considerably from those obtained at zero separation distance. Thus, the pressure drag coefficients for the cone and the afterbody increased and decreased, respectively, as the two bodies were separated.

5. The results based on integrated pressure drag indicate that extraction of a payload from a conical forebody by means of an attached inflatable decelerator is possible provided that the mass of the payload plus decelerator is not too great. For Mach numbers of 0.70 or less, the mass of the payload plus decelerator must be less than 3.5 times the mass of the forebody. Additional tes ts are needed to determine the maximum allowable mass of the payload plus decelerator for Mach numbers greater than 0.70.

6. For Mach numbers less than 0.50, adding the burble fence to the afterbody causes the flow separation point to be well defined and located at the maximum diameter of the fence, whereas for Mach numbers of 0.50 and above, flow separation occurs at the maximum diameter of the configuration with or without the fence attached.
